It takes a long time to practice to affect the face shape. The influence on children's shoes with oval face and pointed face is greater than that on children's shoes with round face or square face. The influence of adult exercises on face shape is extremely limited. The above conclusions are only observed by personal experience and samples around, and there may be survivor bias. Playing saxophone requires the muscles of the lower lip and cheeks. If you practice saxophone in adolescence, I personally think it may have an impact on facial muscles (probably from the fourth grade of primary school to 65438+ 0-2 hours a day). The most intuitive feeling is that the lower lip will be slightly everted, and the muscles on both sides of the lower lip and the lower cheek are obviously more developed. I belong to the type of sharp face, and I don't have much meat on my face. When I was a child, I had a very obvious pointed face and sunken cheeks. But after practicing for several years, I found that my lower cheek was gradually plump and the two muscles under my lower lip became obvious. At that time, as a junior high school student, I was in a sensitive adolescence, and I was still a little anxious about such changes. However, as I grew older, I gradually accepted this change. At that time, I observed several classmates who practiced together and found that the sharp face had a more obvious influence on the face after practicing saxophone. The teacher who taught us saxophone didn't start learning musical instruments until he was an adult. Although I have been practicing for many years, I can hardly see the muscles of my lower lip and lower cheek. Muscles can only grow when they encounter resistance movement, and there is no other way. Playing saxophone is just blowing into the mouth, not doing resistance exercise, so it will only make the muscles sour, but it will never make the muscles grow.
